The attractions prepared by PWPW especially for the Picnic proved extremely popular. At the PWPW stand, visitors could make a sheet of handmade paper with a special watermark, personalise a plastic card or make a number on a commemorative ID card using a pre-war manual printing machine, the so-called 'bostonka'. The greatest fun was had by the youngest visitors to the mobile printing works, but even the older ones, with a twinkle in their eye, turned for a moment into producers of watermarked paper or personalised plastic ID cards.
